GE Zoneline AZ58H12DAD Owner's Manual And Installation Instructions page 13

Use the correct wall case
This unit is designed to be installed in a GE plastic or
insulated metal wall case. This minimizes condensation
from forming on the room side of the case.
If the current wall case is not insulated, you can reduce
the possibility of condensation forming by installing
insulation kit RAK901L, available where you purchased
the unit.
Use the correct outdoor grille
You should use the outdoor grilles shown on the
"Essential Elements" label on the top of the unit.
• If an existing grille is not replaced, capacity and
efficiency will be reduced and the unit may fail to
operate properly or fail prematurely. A deflector kit,
RAK40, may be used with grilles that were not designed
for your new GE Zonelines. The RAK40 contains air
deflectors and gaskets that mount to the unit to direct
the hot exhaust air away from the air intake to allow
the unit to function properly. The grille must have
a 65% minimum free area.
• Any vertical deflectors in the existing rear grille should
be removed to decrease condenser air recirculation
which can cause the unit to "short-cycle" and lead
to premature component failure.
